'Reed' in the Bible

All the inhabitants of Egypt will know that I am Yahweh, because they have been a staff of reed to the house of Israel.

He brought me there; and, behold, there was a man, whose appearance was like the appearance of brass, with a line of flax in his hand, and a measuring reed; and he stood in the gate.

Behold, a wall on the outside of the house all around, and in the man's hand a measuring reed six cubits long, of a cubit and a handbreadth each: so he measured the thickness of the building, one reed; and the height, one reed.

Then came he to the gate which looks toward the east, and went up its steps: and he measured the threshold of the gate, one reed broad; and the other threshold, one reed broad.

Every lodge was one reed long, and one reed broad; and [the space] between the lodges was five cubits; and the threshold of the gate by the porch of the gate toward the house was one reed.

He measured also the porch of the gate toward the house, one reed.

I saw also that the house had a raised base all around: the foundations of the side rooms were a full reed of six great cubits.

He measured on the east side with the measuring reed five hundred reeds, with the measuring reed all around.

He measured on the north side five hundred reeds with the measuring reed all around.

He measured on the south side five hundred reeds with the measuring reed.

He turned about to the west side, and measured five hundred reeds with the measuring reed.
